Comments:SKE 101, Lee 1958, 112. An Eastern isogloss. The Jpn. *kǝ̀tǝ̀ seems a good match, but within Japanese it is rather hard to separate from the homonymous *kǝ̀tǝ̀ 'word, speech' (see *gĕ̀rè(bV)). This is probably a secondary merger, but responsible for the irregular accent correspondence between Kor. and Jpn.
